Two men plead guilty to Harvard Medical School campus explosion conspiracy

Two Massachusetts men pleaded guilty on Apr. 15 in federal court in Boston to conspiring to damage a building on the Harvard Medical School campus using a large commercial firework.

Logan David Patterson, 18, of Plymouth, and Dominick Frank Cardoza, 21, of Bourne, each admitted guilt to one count of conspiracy to damage by means of an explosive. U.S. District Court Judge Angel Kelley scheduled sentencing for Aug. 4. The two were arrested and charged in November last year.

According to court documents, surveillance cameras captured Patterson and Cardoza walking toward the campus at about 2:23 a.m. on Nov. 1 wearing face coverings and dark clothing. They were seen lighting roman candle fireworks before climbing over a fence into a construction area around the Goldenson Building and then onto its roof. At approximately 2:45 a.m., an explosion triggered a fire alarm on the fourth floor where they had detonated a commercial firework inside a wooden locker in the research laboratory of Harvard Medical School’s Department of Neurobiology.

Further footage showed them visiting another floor before leaving through an emergency exit and discarding their clothing as they fled toward Wentworth Institute of Technology's campus after attending Halloween activities there.

The charge carries up to five years in prison, three years supervised release, and up to $250,000 fine. Sentences are determined by federal district court judges according to U.S. Sentencing Guidelines and relevant statutes.
